This is a font that has lots of designs for square tiles spread over 18 fonts, showing various geometric shapes, mostly dots and squiggles, and it follows a quite simple system. They all have just A-Z and a-z characters, with the main designs on A to X and a to x, plus a few on punctuation marks and some numbers.

Upper Case is a coloured tile with white symbols, and the lower case letter is the negative of that - a white tile with coloured symbols. Full details of the layout system are in the Instructions file in the Gallery which can be viewed and downloaded - it’s quite simple. And the images in the Gallery will give a good selection of the shapes available. Or you can type various letters into the text box to get the idea.
